The War on Britain's Roads (BBC Documentary / tabloid tv)

Depends on what you mean by 'the issue'. There's no one big issue, unless you talk about the high-order concept of transport (in)justice which covers all of these issues.

There's a complex of causes which come together in certain symptoms that are perceived by some as more crucial to deal with than the causes.

For instance, the huge need to travel, which in turn is caused by certain factors like property prices and de-localised economies, causes irritation with traffic conditions and fatigue/lack of attentiveness which in turn lead to discourteous and/or aggressive behaviour; you can only push people so far. One of the tragedies is that the perpetrators of the occasional assaults and collisions that occur are often the worst victims of motor dependence and, like many victims, transfer this onto others to turn them into victims, too, whether they want to or not.

Another issue is that people are constantly told to use tools not fit for purpose because they are associated with status or wealth. Driving motorised carriages around can be great fun, but they are remarkable unsuited for routine use around dense settlements. In fact, before motorisation came around, most people would have avoided use of carriages as much as they could and only used them when fit for purpose. Of course, that sort of pointless activity then also increases risk to others. Abuse of technology is a terrible thing.

All of these little absurdities to which we subject ourselves every day just mount up, but never make up just 'one issue'. Single issues are easily dealt with most of the time, and the reason why the complex of problems still exists as it does is because if you were to untangle it you would have to start from so many different ends; slashing it like Alexander slashed the Gordian knot just wouldn't cut it.
Oliver, you talk like a politician i.e. can't you just get straight to the point?

It's quite simple: whatever vehicle you are in charge of - obey the rules/law of the road or get sent to prison for being a twat.

How difficult is that?
